Bug#284783: kernel-image-2.6.9-1-686-smp: Kernel oops possibly related to kswapd
Package: kernel-image-2.6.9-1-686-smp
Severity: grave
Justification: causes non-serious data loss
Under normal use (running kde, konqueor etc) my kernel oops causing the
machine to freeze requiring a hard reset. From looking at the oops
message (which is attached) i suspect it has something to do with
kswapd.
